The invention relates to a guiding device for guiding a blown film between a film blowing die and a take-off roller device, comprising at least two lateral guides located opposite one another for laterally guiding the blown film, wherein at least one lateral guide is provided with a first guide segment and a second guide segment, which are connected to one another in an articulated manner. At least one lever kinematics is provided, which is in drive connection with a drive device, and which is interconnected with the two guide segments such that when the drive device is actuated by way of the lever kinematics, the angles of attack (αa, αe) of the two guide segments to the conveyance direction (F) of the blown film can be varied. |
